debconf-loadtemplate owner file [file ..]
Loads one or more template files into the debconf database. The first parameter specifies the owner of the templates (typically, the owner is the name of a debian package). The remaining parameters are template files to load.
This program should never be used from a maintainer script of a package that uses debconf! It may however, be useful in debugging, or to seed the debconf database.
